Dimensiones de la malla de cálculo – Serie C Malla obtenidos (a partir del programa GEO) fueron los siguientes: La longitud del canal considerado fue de 600 m. Valores de y para la discretización del dominio – Serie C Malla de elementos finitos – caso C3Įl paso longitudinal x se eligió de 4 m para todos los casos, tomándose los siguientes Malla de elementos finitos – caso C1įigura 194. Inestabilidades numéricas en la solución, se trabajó con tres batimetrías diferentes, unaįigura 192. Para evitar procesos de secado – humedecimiento de elementos, que pudieran provocar Misma un ejemplo de la graficación de SMS se puede ver en las gráficas siguientes (Figuraġ92 a Figura 194), donde se muestran las mallas de elementos finitos con un código deĬolor (escala de grises en la impresión) para distinguir la cota de fondo, para los dos La interfaz SMS, permitiendo de ese modo verificar en forma expeditiva la certeza de la Través del programa GEO (ver 7.2.1) la geometría así generada, fue visualizada a través de The knowledge of ancestral peoples is retaken as an important knowledge in their relationship with nature and to face climate change culture that must be confirmed by science.Se aplicó el modelo RMA2 a una batimetría prismática, de sección compuesta generada a Through the results obtained, a field of research is intuited when modeling reticles of channels for the use and management of water. In this way it was discovered that the channel lattice is a solution to the equations of a shallow water joint. It was also noted that the reticle is an efficient way to dissipate energy.

When passing the water through the reticle it was observed, in a 2D simulation with the Iber v2.5 software, that the draft remains constant. To model the grid the geometry of the flow networks used in geotechnics was drawn, the networks are an engineering solution to the Laplace equation. Applying the equations of shallow water can simulate the hydrodynamic behavior and dissipation of energy by passing a flow in a lattice of channels. To give the reason for the mentioned knowledge, when using channel lattices for their plots, it is necessary to model them using flow equations. The knowledge of ancestral peoples is retaken as an important knowledge in their relationship with nature and to face climate change culture that must be confirmed by science. In this paper, the results obtained by uni-dimensional model (HEC-RAS) and two-dimensional

The used models reproduce the water discharge generated by a possible failure of dam number 1 of the 5th District of the Segarra-Garrigues Irrigation Project in the Ebro river basin in Spain.ĪbstractThe development of more and more potent computers and the recent research in the field of hidroinformatics makes possible the free surface flow modelling in two dimensions caused by earthen dam failures. The comparison is made by analyzing the effect of these hypothesis in the downstream flow hydrographs.

The use of the HEC-RAS software assumes the hypothesis of unidimensionality to be true, no infiltration and existence of a minimal initial flow. In this paper, the results obtained by uni-dimensional model (HEC-RAS) and two-dimensional model (CARPA) are compared.

The result is a flow and sediment modelling system for rivers and estuaries that uses advanced numerical schemes, robust and stable, which are especially suitable for discontinuous flows taking place in torrential and hydrologically irregular rivers.ĪbstractThe recent requirements of Spanish regulations and directives, on their turn based on European directives, have led to the development of a new two dimensional open channel flow modelling tool.

The simulation code has been integrated in a pre-process and post-process interface based on GiD software, developed by CIMNE. The tool, named Iber, combines a hydrodynamic module, a turbulence module and a sediment transport module, and is based in the finite volume method to solve the involved equations. AbstractThe recent requirements of Spanish regulations and directives, on their turn based on European directives, have led to the development of a new two dimensional open channel flow modelling tool.
